Hi Rehan, I've been subscribed to your blog for a while and love it! I'm using ReactiveUI validation in a WPF project, and I was wondering if it's possible to keep the entities clean (I've only decorated them with data-annotations attributes or IValidatoableObject implementations), and perform all validation logic in the VM, all this while binding directly to the entities (i.e. exposing them as a whole via a property in the VM, not proxying the properties individually in the VM.

I'm not familiar with ReactiveUI validation. I prefer simple methods to attributes personally.

What about limiting to types like a string can only be numbers. verifying dates, decimal inputs, etc.
